For the baked beans: Heat a large cast-iron skillet over medium. Add the reserved bacon grease and the onions and garlic; cook, stirring occasionally, until the onions are tender, 10 to 15 minutes. Pour in the beans and stir. Add the raisins, maple syrup, bacon, chili powder and some salt and pepper, and stir to combine. Cook for about 20 minutes, until thick, stirring often to avoid sticking. Meanwhile, make the topping.
For the puffed rice topping: In a bowl, mix together the rice cereal, hamburger buns, bacon, melted butter and some salt and pepper. Pour into a medium cast-iron skillet and toast over medium heat, stirring, until light brown, about 15 minutes. Pour the topping over the beans and enjoy.
